Magnetic resonance imaging (MRI), also known as nuclear magnetic resonance imaging, is a scanning technique for creating detailed images of the human body.
The scan uses a strong magnetic field and radio waves to generate images of parts of the body that can’t be seen as well with X-rays, CT scans or ultrasound
Magnetic Resonance Imaging (MRI) is an imaging modality that uses non-ionizing radiation to create useful diagnostic images. In simple terms, an MRI scanner consists of a large, powerful magnet in which the patient lies. A radio wave antenna is used to send signals to the body and then a radiofrequency receiver detects the emitted signals. These returning signals are converted into images by a computer attached to the scanner. Imaging of any part of the body can be obtained in any plane.
Why Would You Get an MRI?
An MRI helps a doctor diagnose a disease or injury, and it can monitor how well you’re doing with treatment. MRIs can be done on different parts of your body. It’s especially useful for looking at soft tissues and the nervous system.
An MRI of the brain and spinal cord looks for:
- Blood vessel damage
- Brain injury
- Multiple sclerosis
- Spinal cord injuries
An MRI of the heart and blood vessels looks for:
- Blocked blood vessels
- Damage caused by a heart attack
- Heart disease
- Problems with the structure of the heart
An MRI of the bones and joints looks for:
- Bone infections
- Damage to joints
- Disc problems in the spine
- Neck or low back pain with nerve signs
MRIs can also be done to check the health of these organs:
- Breasts (women)
- Ovaries (women)
- Prostate (men)
